DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bridge mechanism for a guitar, and more particularly to a bridge mechanism for a guitar having a pressure-sensitive pickup.

[0002]

2. Description of the Related Art In acoustic guitars and the like,
As shown in FIGS. 19 and 20, the guitar string 100
One end thereof is held by a bridge mechanism 110 arranged on the surface of the upper body 102 of the guitar body 101, and the other end is wound around a tuning bolt (not shown) of the head and stretched.

The bridge mechanism 110 includes a bridge main body 111 disposed on the surface of the upper shell 102 and a string support member disposed in the string support member accommodating portion 112 of the bridge main body 111 for holding each guitar string 100. (Saddle member) 115
And one end of each guitar string 100 supported by the string support member 115 is integrally fixed to the string stopper hole 114 of the bridge body 111 by a plurality of fixing pins 120. Reference numeral 103 shown in the figure represents a bridge plate (bridge pad) for reinforcing the upper plate 102. The illustrated bridge mechanism 110 is used for a flat-top guitar in which the distance between a guitar string and a guitar body is relatively narrow among acoustic guitars. A bridge mechanism (double-girder bridge mechanism) equipped with a vertical adjustment mechanism that can be adjusted for the height of the strings is used for arch top guitars, etc., which are fixed by the method but the distance between the guitar strings and the guitar body is relatively wide. There are many.

In recent years, as shown in the figure, a pressure-sensitive pickup (also called a piezo pickup) 125 composed of a pressure-sensitive element is incorporated below the string support member 115 of the bridge mechanism 110, and the string support member 115 is interposed therebetween. The pressure-sensitive pickup 125 is compressed and expanded by the transmitted string vibration of the guitar string 100, thereby generating an electric signal and extracting the pickup output (electric sound). Instead of taking out the pickup output by the pressure-sensitive pickup 125, an electromagnetic pickup device (magnetic pickup device) having a coil and a magnet and generating an electromotive force by virtue of an electromagnetic induction action with the vibration of the guitar string is incorporated in the guitar body. Sometimes the pickup output is taken out.

In the case of using the pressure-sensitive pickup 125, since the string vibration is physically picked up, the output sound has a sharp rise, the attenuation is smooth, and the sound of a non-magnetic nylon string or the like is also generated. Can be picked up,
Further, since no coil is used unlike the electromagnetic pickup device, no induction noise is picked up.

However, in the bridge mechanism 110 having the conventional pressure-sensitive pickup 125, the entire side surface 116 of the string supporting member 115 (however, the bridge body 11
1 Except for the part protruding from the surface. ) Is the bridge body 11
It is in direct contact with the inner wall surface 113 of the first string support member accommodating portion 112. Therefore, most of the string vibration from the guitar strings 100 leaks from the string supporting member side surface 116 to the bridge main body 111 near the guitar strings 100, more specifically, at a position immediately below each of the guitar strings 100, and Only a part of the vibration is transmitted to the pressure-sensitive pickup, and there is a problem that the efficiency of propagating the string vibration to the pressure-sensitive pickup 125 is poor.

As means for solving the above problem, as shown in FIG. 21, the distance between the inner wall surfaces 133 of the string support member accommodating portion 132 of the bridge body 131 is determined by changing the distance between the string support members 13.
5 is filled with resin M between the string supporting member 135 and the pressure-sensitive pickup 145 and the string supporting member accommodating portion 132, so that the side surface 136 of the string supporting member 135 and the bridge main body are filled. It is conceivable that a gap 150 is provided between the inner wall surfaces 133 of the string support member housing portion 131 of FIG. However, according to this means, not only the strength of attachment (stability) of the string support member 135 to the bridge body 131 is insufficient, but also the resin M deteriorates with time and the string of the resin
The resin M is crushed due to insufficient strength against the force acting in the tension direction X of the string via the string support member 35 and the string support member 13
5 is inclined in the string tension direction X and the side surface 1 of the string support member 135
There is a possibility that the string vibration may leak to the bridge main body 131 at the contact portion between the 36 and the inner wall surface 133 of the string support member accommodating portion 132. In FIG. 21, reference numeral 102 denotes a top of the guitar body, 103 denotes a bridge plate (bridge pad) for reinforcing the top 102, 130 denotes a bridge mechanism, 134 denotes a string stopper hole formed in a bridge main body 131, and 140 denotes a string stopper hole. A fixing pin for fixing the guitar string 100.

FIG. 1 shows an acoustic guitar 3 having a bridge mechanism 40 according to an embodiment of the present invention.
0 is shown. This acoustic guitar 30
Generates a tone by the resonance of the guitar body 31. The upper back 32, the back upper 33 and the side plate 34 of the guitar body 31 resonate and amplify the vibration sound of a plurality (six in the figure) of each of the guitar strings S. A hollow resonance box part for it.

Then, the acoustic guitar 30
In one embodiment, one end of each guitar string S is held by a tuning bolt 36 of a head 35, and the other end is held by a bridge mechanism 40 according to an embodiment of the present invention, the other end of which is arranged on a shell 32. It is stretched by doing. Reference numeral 37 shown is a sound hole. The acoustic guitar 30 of this embodiment is classified as a flat-top guitar in which the interval between each guitar string S and the upper shell 32 of the guitar body 31 is relatively small. Hereinafter, an embodiment of the bridge mechanism 40 will be described in detail.

The bridge mechanism 40 is configured to convert the string vibration of each guitar string S into an electric signal and output the electric signal as an electric sound, as shown in FIGS. The bridge body 41 and the string support member 5
1, a pressure-sensitive pickup 61, and an intermediate member 71. Reference numeral 38 in FIG. 4 denotes a bridge plate (bridge pad) for reinforcing the upper 32.

First, the bridge main body 41 will be described. The bridge main body 41 is a portion for attaching the bridge mechanism 40 to the surface of the upper 32 of the guitar body 31. The bridge body 41 in this embodiment is the same as the guitar string S
A plate-like material made of wood or the like, which is long in the lateral direction (direction orthogonal to the tension direction X of the string) Y, and the back surface of which is fixed to the surface of the upper 12 with an adhesive or by bolting as appropriate. Fixed by method. A string support member accommodating portion 42 for a string support member 51, which will be described later, is provided at a front portion of the bridge main body 41, and at a position corresponding to each guitar string S at a rear portion of the accommodating portion 42, A plurality of (six in this embodiment) string stopping holes 46 are provided. In this embodiment, the string supporting member accommodating portion 42 is formed of a groove that is long in the lateral direction Y with respect to the guitar string S, but is not limited thereto. The space for the string support member may be constituted by a space partitioned (or surrounded) by the wall portion of the string support member.

The string support member 51 is for supporting each guitar string S, and is made of synthetic resin such as urea resin or cow bone. The string support member 51 is provided in the string support member accommodating portion 42 of the bridge main body 41. In this embodiment, the string support member 51 is formed of a single plate-like body, and a plurality (6 in FIG.
) String contact portions 55.

One end of each guitar string S supported by the string support member 51 is integrally fixed to a string stopper hole 46 formed in the bridge main body 41 by a plurality of (six in the figure) fixing pins P. It has become so. The fixing pin P in this embodiment has a notch Pa for accommodating the string along the axial direction.
By inserting one end of the guitar string S together with the fixing pin P into the string stopper hole 46 of the bridge body 41, the guitar string S is
6 and the fixing pin P.

The pressure-sensitive pickup 61 detects vibration of the guitar string S, converts the vibration of the string into an electric signal, and outputs the signal as a pickup output (electric sound).
It is composed of a known pressure-sensitive element. The pressure-sensitive pickup 61 is provided below the string supporting member 51.
1 is provided so as to be in contact therewith.

The pressure-sensitive pickup 61 generates an electric signal by compressing and expanding by vibrating the strings of the guitar string S transmitted through the string supporting member 51 to generate an electric pickup signal. The rise is sharp,
The damping is smooth, and it is possible to cope with the case where a string made of a non-magnetic material such as a nylon string is used.
The pressure-sensitive pickup 61 is connected to a circuit board or the like (not shown) via a conducting wire (not shown), and further connected to an electronic device such as an amplifier via a jack J and a cable C (see FIG. 1). Connected.

The intermediate member 71 increases the propagation efficiency (transmission efficiency) of the string vibration from the guitar string S to the pressure-sensitive pickup 61, and securely fixes the string support member 51 to the string support member accommodating portion 42 of the bridge body 41. It is to make it. The intermediate member 71 is interposed between the inner wall surface 43 of the string supporting member accommodating portion 42 of the bridge main body 41 and the side surface 52 of the string supporting member 51. In this embodiment, the pair of intermediate members 71, 71 are disposed on both sides of the string support member 51. However, the intermediate members may be disposed on one side of the string support member 51. However, in order to further increase the propagation efficiency of the string vibration, it is preferable to arrange the intermediate members 71 on both sides of the string support member 51 as in this embodiment. Each of the intermediate members 71 in this embodiment is formed of a thin plate. The thickness b3 of the intermediate member 71 (the length of the string tension direction X of the contact portion 13 described later) b3 is the thickness b2 of the string support member 51 and the inner wall surface of the string support member accommodating portion 42 of the bridge body 41. 43, 43 are determined in consideration of the distance b1 between them.

A non-contact portion 72 that is not in contact with the side surface 52 of the string support member 51 is provided at least at a position substantially directly below each guitar string S on the side wall surface of the string support member of the intermediate member 71. In this embodiment, the non-contact portion 72 is constituted by a concave portion having a predetermined width k1. The width k1 of the non-contact portion 72 allows a slight deformation of the portion of the string support member 51 near the guitar string in the string tension direction X during string vibration,
And a contact portion 73 of the intermediate member 71 with the string supporting member side surface 52.
, That is, the stability of the string support member 51 with respect to the bridge body 41 is sufficient. Specifically, the width k1 is set to １ ／ or more of the pitch q between strings.
In this embodiment, the center in the width direction of the non-contact portion (concave portion) 72 is set to be substantially immediately below each guitar string S.

As described above, the non-contact portion 72 that does not contact the string supporting member side surface 52 is provided at least in the intermediate member 71 at a position substantially directly below each of the guitar strings S. If a gap is provided between the intermediate member 51 and the intermediate member 71, leakage of string vibration to the bridge body 41 can be reduced, and the pressure-sensitive pickup 6 of string vibration can be provided.
The propagation efficiency to 1 is dramatically improved.

Here, the material of the intermediate member 71 is not particularly limited, but the material of the intermediate member 71 is preferably a metal or the like having excellent rigidity. By doing so, the strength of the intermediate member 71 with respect to the tension of the guitar string S (the strength with respect to the force acting in the tension direction X of the string acting from the guitar string S via the string support member 51) becomes sufficient. At the same time, leakage of string vibration from the intermediate member 71 to the bridge body 41 can be further reduced.
